Review on 🔧 NANPU Filter Regulator Lubricator with NPT Fittings by Jeff Drollinger

I didn't filter much water, if any. Luckily I had a built-in spray gun filter, otherwise I wouldn't have been able to paint at all. This filter let enough water through to completely saturate the built-in filter, and eventually some of the water ended up in my paintwork. The O-ring can also get stuck in the gap between the drain and the plastic, causing a leak. Another problem is the car oiler. It works fine when you open it, but it doesn't close completely and jumps a bit when you turn it off. The only thing that works halfway decent is the controller. This combo isn't exactly the best device, but I think it can be used on a budget. Just make sure you try to keep water out of the lines to get an in-line filter as I don't think I've ever seen it pick up moisture.
